Abstract
A fuel cell system, comprising: a measurer that measures an impedance of the fuel cell; a controller that controls an operation state of the fuel cell; and an acquirer that acquires a dryness degree of the fuel cell from the measured impedance when the operation state is a first operation state, and acquires the dryness degree of the fuel cell as a wet state when the operation state is a second operation state in which a water balance is more than the first operation state.
